I don't understand why my internet on my computer constantly disconnects?

Hey guys, so I recently reformatted my computer and ever since doing so, my computer has experienced some disconnections... the only way to fix it is to either

A. Wait it out which takes about 10 minutes or so.

B. Refresh the connection by disabling my Ethernet port and re-enabling it.

At first, I thought it was the internet itself, but no other computer/device is experiencing this problem. I even checked Speedtest.net I'm still easily getting about 7MB/s (which is what I'm paying for so thats all in the green)

so then I thought maybe my network drivers needed to be updated, which sadly hasn't done anything... so I thought maybe it was a virus or something, however scans show up clean nor have I really downloaded anything or been on something that has viruses ever since the format... I really just don't understand why its doing this :( any suggestions?

this is a desktop. I could be wrong, but I don't think its the cable itself considering that this only started to happen after I formatted the computer.
